GENERAL DESCRIPTION

The AD9102 TxDAC® and waveform generator is a high performance digital-to-analog converter (DAC) integrating on-chip pattern memory for complex waveform generation with a direct digital synthesizer (DDS). The DDS is a 14-bit output, up to 180 MSPS master clock sine wave generator with a 24-bit tuning word, allowing 10.8 Hz/LSB frequency resolution.
